@ILoveJDD - looking at the encoding in the log you show - are you sure those are not "curly" apostrophes rather than standard ones?

Nope. Before I downloaded metadata, I did a search and replace for curly apostrophes to regular ones. I believe %25 corresponds to the % sign so I'm guessing it's being double encoded or something. Perhaps the plugin searches for "The Halfling%27s Gem" and the website is translating it as "The Halfling%2527s Gem".
